Modeling the response of precast, prestressed concrete ...

PCI Journal 78 Precast, prestressed concrete hollow-core slabs have gained wide popularity in recent years due to their numerous advantages over other forms of construction. These advantages include aesthetics, speed of construction, efficient use of space, and flexibility. Structural fire safety is a primary consideration in buildings; thus building codes specify fire-resistance rating ...

This nonlinear finite-element model uses a transient thermostructural analysis to trace the response of typical hollowcore slabs under fire conditions. The model accounts for temperature-induced degradation of properties of concrete and prestressing strands, cracking in concrete, material and geometrical nonlinearities, realistic fire, load and restraint conditions, and different failure limit ...

Seismic Performance of Precast Prestressed Concrete Piles ...

ATC3‐06 placed strict limitations on the use of precast prestressed concrete piles in severe seismic regions. Two reasons contributing to the decision were the poor level of understanding of the curvature capacity of such piles and the magnitude of the curvatures which are likely to be imposed on them by a moderate to severe earthquake.
